Pyrite Depression in Copper Flotation

The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyritecopper, you need to bring the plants pH up to the other side right side of the PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite .
